TEVA is used by clicking buttons on the current page. Here is a list of the buttons on the Configuration page with a
description of their use. English labels will be used here. The keyboard shortcuts are given between the []-brackets (might depend on language).
See also the Overview of Main page.

Many of buttons are radio type push buttons. When clicked, they remain "pushed down" until another button is pushed. The state
of these button is remembered between invocations of TEVA. Buttons on a (light) gray background are grouped together, like the language choice buttons or the
Frequency buttons.

The display of spectral features should be reduced to exclude irrelevant detail.

is set to 5 kHz or below, the sample frequency will be set to 11.025 kHz (down from 22.050 kHz).

Speakers: Speaker data tables and recording duration
